Sample has stressed that permanent deacons should not regularly preach at Mass; rather they should preach at other services and serve the Church in the course of their daily witness to Christ. His 19-page letter, titled “The Deacon: Icon of Jesus Christ the Servant”, cited the principle that the one who presides at a liturgical service or who is the principal celebrant at Mass should also give the homily: “This should be the ordinary practice." Deacons should preach the homily at Mass “for some identifiable advantage for the faithful in the congregation, but not on a regular basis.”[9]
